Out of ideas, help needed please

My RIRs started laying this week (19 wks old) and I find eggs everywhere but in the nestboxes.

I put the boxes in the coop a couple weeks ago with 2 golf balls in each. The girls checked out the boxes, left a few downy feathers in each, and then ignored them, as I expected. All good so far.

The day before the first egg, the nestboxes were trashed. Litter everywhere and golf balls rolled down the ramp into the yard. I tidied everything up and had a repeat experience 3 more times before finding the first egg ON TOP of the boxes. With 4 of them laying now, not one egg is in the box! The closest was about 6 inches away.

I switched out the milk crates I was using for nestboxes and put in larger storage containers this morning, fresh litter, golf balls, clean and pretty. No luck and poopy eggs!
